Positron emission tomography (PET) with (18)F-FDG shows promise for gynecologic cancers, particularly in detecting nodal disease and evaluating uncertain findings. Further research is needed to confirm its impact on survival and refine its clinical application.

Area of Science:

  • Nuclear Medicine
  • Oncology
  • Radiology

Background:

  • (18)F-FDG PET imaging is underutilized in gynecologic malignancies, with its clinical role not yet fully established.
  • Current applications show potential in specific scenarios within cervical, ovarian, and endometrial cancers.

Purpose of the Study:

  • To review the current role and potential applications of (18)F-FDG PET imaging in gynecologic malignancies.
  • To evaluate its utility in diagnosis, staging, treatment response monitoring, and surgical planning.

Main Methods:

  • Systematic review of existing literature on (18)F-FDG PET use in cervical, ovarian, and endometrial cancers.
  • Analysis of diagnostic accuracy, particularly for nodal metastasis and recurrent/residual disease.
  • Evaluation of the sentinel lymph node (LS) technique in surgical management.

Main Results:

  • High sensitivity of (18)F-FDG PET for nodal disease detection in cervical cancer, especially when conventional imaging is ambiguous.
  • (18)F-FDG PET shows promise for evaluating recurrent or residual disease in ovarian and endometrial cancers.
  • The sentinel lymph node technique is encouraging for surgical planning in cervical, endometrial, and vulvar cancers, potentially reducing extensive dissection.

Conclusions:

  • (18)F-FDG PET imaging has a defined role in specific gynecologic cancer scenarios, particularly for equivocal findings and nodal staging.
  • Further data are required to confirm survival benefits and consolidate its role in treatment response monitoring.
  • The sentinel lymph node technique shows promise for optimizing surgical management, but larger studies are needed to establish clinical utility.
